+Summary: Allow simple return statements inside iterators
+
+I think we should allow an iterator to return (without an object), to make
+programing simplier. The following code shows an example of a possible use
+of this feature:
+
+		static IEnumerator GetNews (int begin, int size) {
+#if __V2__
+			XPathNavigator nav = new XPathDocument ("myxmlfile").CreateNavigator ();
+			nav.MoveToFirstChild ();
+			XPathNodeIterator itr = nav.SelectChildren (XPathNodeType.Element);
+
+			for (int i = 0; i < begin; i++) {
+				if (!itr.MoveNext ()) return;
+			}
+
+			for (int i = 0; i < size; i++) {
+				yield new NewsStory (itr.Current.Value); 
+				if (!itr.MoveNext ()) return;
+			}
+#else
+#error Needs Version 2 features.
+#endif
+		}
